1 3M™ BairHugger™ Warming Unit Model775

Operator’sManual

Introduction

Description of the 3M™ BairHugger™ Temperature

ManagementSystem

The BairHugger temperature management system consists of a

Model 775warming unit (with optional rolling stand, and other

accessories) along with a 3Mwarming blanket, BairHugger warming

gown, or the 3M™ Ranger™ 241blood/fluid warmingset.

The BairHugger warming unit is attached to the warming blanket or

warming gown by means of a flexible hose. Warm air is generated

in the warming unit and flows through the warming unit hose and

into the blanket or gown. Depending on the model, the 3Mblanket

or gown is placed either around, over, or underneath the patient.

Small perforations on the blanket or gown allow the warm air to be

dispersed over the patient. For blood/fluid warming applications, the

Model 241blood/fluid warming set is inserted in the warming unit

hose. When the warming unit is turned ON and a temperature setting

is selected, warm air flows over the Model 241tubing and warmed

blood/fluid exits from the distal end of the tubing. For additional

information on 3Mblankets, gowns, the 241warming set, or other

accessories visit us online atbairhugger.com.

This manual includes operating instructions and warming unit

specifications for the Model 775warming unit. You can use the

Model 775warming unit in all clinical settings where the patient may

feel too warm or too cold; including the operating room to provide

patient temperature management. For information about using

3Mblankets, gowns or the 241blood/fluid warming set with the

Model 775warming unit, refer to the respective Instructions forUse.

Indications

The BairHugger temperature management system is intended

to prevent and treat hypothermia. In addition, the temperature

management system can be used to provide patient thermal comfort

when conditions exist that may cause patients to feel too warm or too

cold. The temperature management system can be used with adult

and pediatricpatients.

• The BairHugger temperature management system should

What to Do If a Fault Conditionoccurs

The Model 775warming unit software recognizes several

non-hazardous conditions and reports those conditions as faults.

When a system fault occurs, the software stores the fault code

in memory, the amber Fault indicator light flashes, and an alarm

sounds. The warming unit automatically turns the heater, blower,

and operating mode indicator lights OFF. The control panel will not

respond tocommands.

Note: Pressing any button will silence thealarm.

IF A FAULT CONDITIONOCCURS:

1. Unplug the warming unit and wait for 30-60seconds.

2. Reconnect the warming unit to a grounded power source. The

warming unit will perform the normal power-on-reset sequence

and then enter the Standbymode.

3. Reselect the temperaturesetting.

4. If the warming unit does not return to normal operation, contact

a qualified servicetechnician.

FAQ / 0-8811-8718-34

Frequently Asked Questions (FAQ) on Filtration

What filter is used in the 3M™ Bair Hugger™ Model 775 warming unit?

The Model 775 uses the same lter media as has for many years been used with prior Bair Hugger -700series models. That lter media is

classied on an industry-standard scale as MERV 14 at 48 CFM (cubic feet per minute) under ASHRAE Standard 2012-52.2: Method of

Testing General Air Ventilation Air-Cleaning Devices for Removal Eciency by Particle Size.1,2

What is a MERV rating?

The Minimum Eciency Reporting Value, or MERV, is a measurement scale to rate the eciency of an air lter as a

function of particle size based on the ASHRAE Standard 2012.1,2.1,2-52.2

What is the MERV rating recommended for operating rooms?

ASHRAE Standard 2013-170, Ventilation of Health Care Facilities, provides standards and guidance on the design

requirements for ventilation systems utilized in health care facilities.3 The standard recommends that operating rooms

utilize a lter that is equivalent to MERV 14.3 This MERV rating is specic to the ventilation system in the hospital’s

operating room.

What is the MERV rating recommended for patient warming devices in the operating room?

There is no ltration standard for patient warming devices utilized within the operating room. The ASHRAE Standard is a

standard used to assess lter eciency in health care ventilation systems.

Is a HEPA filter necessary?

No. We are not aware of any evidence or claim demonstrating that a HEPA lter improves patient safety.

What is the ASHRAE 52.2-2012 standard?

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is a global organization

focused on research, education and standards for heating, ventilation, air conditioning and refrigeration. The ASHRAE

standard 20121,2-52.2 provides test methods for air intake lters to ensure standardization in classication and

eciency. For more information on ASHRAE, please visit www.ashrae.org.
